Definition

Hangover is the collection of physical and mental symptoms that occur after a person drinks excessive amounts of alcohol.

Description

A survey found that about 75% of the persons who drank enough to be intoxicated (drunk) sometimes experienced hangover. Although very prevalent, hangovers have not been extensively studied. It is known that ethanol is the primary chemical component of alcohol to produce the effects associated with drinking.
